PayPal Referrals

Have you ever referred a friend to paypal? I have referred tow people so far. It's not really that great you get 0.5% of whatever they get into their account for the first twelve months. For most people I don't think thats alot and 0.5% isn't much, $5 for every $1000 they get. There is a limit of $1000 but I doubt any of my referrals will get $200,000 into their account. If you knew someone that possibly would be getting alot then it could be worth doing. Have you?
